Specification of Letters Patent.

Patented July 24, 1906.

Application filed September 23. 1905. Serial No. 279,818.

1'0 all whom, it may concern.-

Be it known that we, CHARLES H. CooLEY WALTER D. CooLEY, citizens of the United States, residing at Wichita, in the county of Sedgwiok and State of Kansas,

have invented certain new and useful Improvements in Paper-.Foldin Machines, of which the following is a speci 'cation.

This invention relates to machines for folding news apers, pamphlets, circulars, and like artic es required to be reduced to a small package for convenience of handling.

The improvement resides in the novel structural features, which hereinafter will be more particularly set forth, illustrated, and claimed.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a side view of a paper-folding machine embodying the'invention; Fig. 2 is a longitudinal section thereof on the line X X of Fig. 4. Fig. 3 is an end view of the machine, parts being broken away to show more clearly the relative arrangement of the cooperating elements. Fig. 4 is a top plan view of the machine, parts being broken away.

' Figs. 5 to 5 ,'inclusive, illustrate the different steps in the operation of folding. Fig. 6 is a perspect1ve view of the sliding. bars which operate the packer and parts adjacent thereto and cooperating with said bars. a detail enlarged sectional view showing clearly the arrangement of the packer and the yieldable portion of the guide of one of the folders.

Corresponding and like parts are referred to in the following description and indicated in all the, views of the drawings by the same reference characters.

The machine comprises a suitable framework, upon which the working elements are Fig. 7 is mounted according to the capacity and design of the completemechanism. The driveshaft 1 is provided with spur-gears 2 and disks 3 fast thereto, the disks 3 being formed with cam-grooves 4 for operating the folder 5. A shaft 6, paralleling the shaft 1, is provided with spur-gears'7 and 8, fast thereto, the spur-gear 7 intermeshing with the s urgears 2 and receivin motion therefrom. he spur-gears 8 are of. arger diameter than the spur-gears 7 and are formed with .cam-

grooves 9 for actuation of the folder 1.0. A third shaft 11 has fast thereon spur-gears 12, which are in mesh with the spur-gears 8 and in which are formed camrooves 13 for'operation of the folder 14. he several folders 5, 10, and 14 are preferably of similar construction and consist of blades provided at oppositd ends with rollers 15 for cooperation with the respective cam-grooves, whereb the frictional contact is reduced to the smal' est amount possible. The blade 14'gives the initial fold, the blade 5 the second fold, and the blade 10 the final fold. The blades 10 and 14 operate in parallel planes, which are relatively disposed in perpendicular position, whereas the blade 5 operates in a plane at'a right angle to the plane ,of movements of the blades 10 and 14 or in a relative horizontalplane. I The sheet, pamphlet, or the like to be folded is pressed between suitable guides in the folding operations. The working parts are so proportioned as to perform several steps in the folding operation in successive order.

The sheet 16 or like article to be-folded is supported upon a table or bed 17, having a slot 18, positioned to'receive the folder 14, guides 19 and 20 being attached to the under side of said table and arranged-upon opposite sides of the slot 18. The guide 19 1s comparatively 'short, whereas the guide 20 reaches to the plane of the folder 5 and is curved, as shown at 21. The space below the guide 19 is necessary to admit of labeling or otherwise imdpressing matter upon the arti-- cle to be'fol ed, said addressing or labeling being effected by means of a suitable stamp 22 which preferably is of the reversible, type,

so as to receive ink upon its outstroke and impress the reqlliiir d matter upon the part 16 u on its instro e. A glass p ate 23 1s Set H). t e table, bed, or su port 17, so as to'come flush with the top side thereof and is located to admit of the working parts being at all times under observation. A gage 24 is adjustably secured to the support 17 and preferably positions the sheet-or article 16 when the same is fed to the machine either by hand or otherwise to be folded.

The folder 5 operates in a guide 25, of which the lower curved end 21 of the guide member 20 forms a part. A part 26 of the lowermost wall of the guide' 25 is movable, bein pivoted at one end and adapted to yielf at its opposite end, so as to move' with the folder 10 when giving the final fold to the sheet or article 16, said folder engaging the part 26 to carry it upward, thereby con fining said article and preventing unfolding thereof throughout the length of movement incident to the operation of the folder 10 and the delivery of t e folded article into the receiver 27. A spring 28 cooperates with the part 26 o restore it to its normal position as the folde 10 moves downwardly. The receiving end of the guide 29 has its wall flared in opposite directions to facilitate the entrance of the paper 16 or the like in the fold- I ingr operation.

. ce tacle into which the folded articles are end with ahandle 30.

- tending entirely across the machine with de ivered and which is provided at its outer A follower 31 is arranged within the receiver 27 and consists of blocks pressed apart by means of one or more springs whereby said follower ofiers sufficient resistance to insure'pro er compression of the articles when folde so as to insure their lying close together. The receiving end of the receiver 27 is in communication with the ide 29, so as to receive the sheets when fol ed. a

'A'packer 32 is arranged to operate across the path of the guide 29, so as to force the folded sheets thereoverinto the receiver 27 In the referable construction arid as illustrated t s packer consists of a re or bar exboth ends projected to make connection with bars or plates 33, slidable longitudinally on the o posite sides of the machine and which are a apted to receive a reciprocating movement so as to move the packer backward and forward. The bars 33 are spring-actuated and are normally held projected, or with the packer against the material in receiver 27 against the tension of springs 34, by means of dogs 35. The dogs 35 are ivoted to the upper portions of the sides 0 the framework of the machine,'and said dogs are arranged to en a thgp ates or bars 33. Lateral extensions 35 pro ect from the dogs 35 and are adapted to e engaged by trips to be hereinafter describe which tri s are carried by the folder -10, release of the ars 33 to permit the latter to rebound under the action of the springs 34 being eflected by means of the above-mentioned tri mechanism. Arms 36- project from. the older 10 and are movable therewith, constituting trips, and are arranged to come into contact with the extensions 35 of the dogs 35 upon the upward movement of the folder, so as to release the packer and 'hold said packer in such a position e in notches 33 in the adjacent ends ofmit positive engagement permit it to automatically assume a position in the rear of the folded a er, so that u on the return stroke of the ol er 10 the pac er may advance and force the last paper into the receiver .27. j

The stamp 22 for printing the address or other data upon the paper may be of any type'or design and is arranged to be inked by a suitable appliance, such as a pad 37. The stamp 22 is operated by means of a crank 38, journaled in suitable bearings and provided with a spur-wheel 39-, fast to one end or jaw of said crank. A rod or bar 40 connects the crank 38 with the stamp 22.

The bars 33, as before premised, are connected together by the packer or rod 32, and said. bars are provided with slots 33 at the ends remote from thepacker 32. The bar 40, connected-with the crank 38 by the rod or pitman 40, passes through the slots 33 of the bars 33 and is adapted to actuate said bars in order to operate the packer 32 in the manner above described. 'As the stamping mechanism moves toward the folder 10the bar 40 is carried toward the packer until it strikes corresponding ends of the slots 33*,

whereupon it imparts movement to said bars 33, carrying the packer 32 across the guide 29 and transferring a folded article or sheet from said guide to the receiver 27 The dogs 35 automatically engage with the bars 33 when the packer enters the receiver, and thus that it compresses the folded material. As the folder 10 moves upwardly, however, the arms or trips 36 engage the extensions 35 of dogs 35 and disenga e said dogs from the bars 33, permitting the ars to rebound and carry the packer 32 into a position to the left-of'the guide 29 initial to engagement with the aper or article which is being carried upwar 1y by the folder 10. As the folder 10 descends after reaching the limit of its upward movement the stamping mechanism is moving toward the folder 10, and the packer 32,will again be actuated in the manner above described to carry the folded article to the re ceiver 27, moving the bars 33 against the tension 'of the springs 34. By reason of the length of the slots 33 the. packer 32 may renialn in the receiver 27- temporarily, though.

mechanism is returning to itsmore remote position to perform its functlons the stamping so as to hold the spur-gear 39 and cran 38 in given positions and prevent any possible movement thereof during the intervals between the positive operation of the address mechanism. A portlon of the rim or lateral flange 42 is toothed, as shown at 44, to perwith the teeth of the element 39, so as to drive the crank 38 'and positively actuate the address mechanism. The rim or flange 42 is indented at each end of the toothed portion 44, as indicated at 45, to admit of the teeth 44 entering and leaving the toothed portion of the spurgear 39 when meshing and unmeshing. The indentations 4.5 are ance for the end portions of the smooth part 41 in the operation of the machine.

In the initial operation of the machine the paper 16 or analogous article is placed in positi= n upon the table or support 17, being limited in its advance by means of the gage 24. An instant later the folder 1.4 descends and doubles the paper upon itself, as indicated most clearly in Fig. 5-, and when the fold ar 14 reaches the limit of its downward movement the address mechanism or stamp 22 is moved forward and impresses the desired matter upon the folded end portion of the sheet, the folder or blade 14 constituting a support to sustain the pressure of the stamp during its final movement. After the parts 14 and 22 have performed their oflice the folder 5 is shot forward and folds an end portion of the sheet previously doubled, as indicated in Fig. 5 The folder next in turn comes into play and folds the opposite end portion of the sheet, as indicated in Figsf5 and 5, thereby completing the, folding operation. As the folder 10-moves upward the folded sheet is advanced to the stacker and is forced into the latter by means of the packer 32 in the manner specified.
